Answer:

DE = 7.07 RS = 11.04 not congruent

Step-by-step explanation:

Formula:

$d=\sqrt{(x2-x1)^2 + (y2-y1)^2}$

D (5,0) E (0,-5)

$d=\sqrt{(0-5)^2 + ( -5 - 0)^2}$

$d=\sqrt{(-5)^2 + (-5)^2}$

$d=\sqrt{25+25}$

$d=\sqrt{50}$

d= 7.07

R (-5,-5) S (6,-6)

$d=\sqrt{(6-(-5))^2 + (-6 - (-5))^2 }$

$d=\sqrt{11^2 + (-1)^2}$

$d=\sqrt{121 + 1}$

$d=\sqrt{122}$

d= 11.04

The store salsa jars have a height of ten centimeters and a radius of five centimeters. If there is only four centimeters of sal

Romashka-Z-Leto [24]

Answer:

$V=471.24cm^{3}$ (simplified)

$V=150\pi cm^{3}$ (in terms of pi)

Step-by-step explanation:

Since the salsa jar is basically a cylinder, to solve this we are using the formula for the volume of a cylinder:

$V=\pi r^{2} h$

where

$V$ Is the volume of the cylinder (salsa jar)

$r$ is the radius of the cylinder (salsa jar)

$h$ is the height of the cylinder (salsa jar)

We know from our problem that height of the full salsa jar is 10 centimeters; we also know that that there are only 4 centimeters of salsa left in the salsa jar. So, to find the the height of the missing salsa, we just need to subtract the height of the salsa from the height of the full salsa jar: $h=10cm-4cm=6cm$ . Since the radius of the salsa jar never changes, $r=5cm$ .
